     NAME
          dtspcd - CDE Subprocess Control Service

     SYNOPSIS
          dtspcd    [ -debug ] [ -log ] [ -auth_dir directory ]      [
          -timeout num_minutes ] [ -mount_point mount_point ]

     DESCRIPTION
          The daemon for the CDE Subprocess Control service, dtspcd,
          is not intended to be started directly by the user, rather
          it should be started automatically by the inetd daemon (see
          inetd(1M)) in response to a CDE client requesting a process
          to be started on the daemon's host.

     OPTIONS
             -auth_dir  directory
                            The default authentication directory is
                            the user's $HOME directory.  This option
                            allows the system administrator to use a
                            different directory.  Note that directory
                            must be exported to hosts wishing to use
                            the dtspc service.
                            directory - the name of the directory to
                            use for authentication.


             -timeout  minutes
                            By default, the dtspcd process will
                            terminate if it does not have any activity
                            (process start or process stop) for 10
                            minutes and dtspcd has no child processes
                            running.  To change the timeout, set
                            minutes to the desired number of minutes.
                            To force the daemon to not use a timer,
                            set minutes to -1.
                            minutes - the number of minutes for the
                            timer.

             -mount_point  mount_point
                            The file system's mount point is named
                            mount_point.  For example, mount_point
                            could be "/net" or "/nfs".  The daemon
                            sets the environment variable DTMOUNTPOINT
                            to the value of mount_point.  This value
                            of DTMOUNTPOINT will override all other
                            definitions of DTMOUNTPOINT.

             -log           This option turns on logging of status
                            information to the file
                            /var/dt/tmp/DTSPCD.log.  The information
                            logged includes the name of the client
                            host, the client's username, error
                            messages and the name of the file used for
                            authentication.  The default is to not do
                            any logging.

             -debug         This option turns on logging of dtspc
                            protocol to the file
                            /var/dt/tmp/DTSPCD.log.  The protocol
                            information logged includes the name of
                            the protocol and number of bytes in the
                            request.  The default is to not log the
                            protocol.

     AUTHENTICATION
          When a CDE client attempts to connect to a dtspcd daemon,
          the client sends the daemon its username.  The daemon uses
          the username to determine the user's home directory on the
          daemon's host.  The home directory is used during
          authentication and it must be readable by the daemon and
          writable by the client.  Therefore, the user's home
          directory on the daemon's host must be mounted to the client
          host.  If the user's home directory is not readable and the
          -auth_dir command line option is not used, the directory
          /var/dt/tmp will be used.

          To use a directory other than the user's home directory for
          authentication, use the -auth_dir command line option.

     CONFIGURATION
          The dtspcd daemon is an Internet service that must be
          registered in the file /etc/services as follows:

               dtspc      6112/tcp

          and in the file /etc/inetd.conf as follows:

               dtspc  stream  tcp  nowait  root  /usr/dt/bin/dtspcd/usr/dt/bin/dtspcd

     ENVIRONMENT VARIABLE MANAGEMENT
          The CDE Subprocess Control service allows the user and
          system administrator to create files of environment variable
          definitions to be placed in the processes environment before
          a remote process is started.  See dtspcdenv(4M) for more
          information.

     OPERATING SYSTEM DEPENDENCIES
          On HP-UX, the file /usr/adm/inetd.sec may be used to control
          access to the dtspcd daemon.  See inetd.sec(4) for more
          information.
